A high-frequency welding machine is a device that uses the resistance heat generated by high-frequency current passing through the contact surface of workpieces to perform welding.
It is a solid-state resistance welding device that achieves interatomic bonding between metals. The working principle of a high-frequency welding machine is based on the skin effect and proximity effect of high-frequency current.
Unlike other welding machines, the function and application of a high-frequency welding machine are not limited to welding. High-frequency welding machines can be used not only for welding various metal materials, but also for processes such as through-heating, smelting, and heat treatment.
